What component should I use to display enabled/disabled state?

I have been wondering what component I should use to display state of enabled/disabled behaviours in WinForms.

For example I have function that returns state of 2 different processes.
And I want to display like green and red color on GUI, so that user could easily know which process has wich state.

In Java I have used

ProgressBar

, like setting it to 100 and 0, so it represents the state of that process. But as for now, I have moved to C#, so I would like to know what components you use for this purpose, maybe there is something better to use.
